PENGARUH PHOTOPERIOD BERBEDA TERHADAP PERTUMBUHAN DAN KELANGSUNGAN HIDUP BENIH IKAN BETOK (Anabas testusdineus)

Climbing perch (Anabas testudineus) is a native freshwater fish species in Indonesia that inhabits swamp, rivers and lakes. This species is known to have relatively slow growth and development. One efforts to increase its growth is through environmental manipulation with the lighting method (photoperiod) given to the rearing media. Photoperiod or duration of light exposure, is an environmental factor that can directly influence fish feeding behavior. This study was conducted to determine the best photoperiod for the growth and survival of climbing perch fingerling. This study used a completely randomized design (CRD), with 5 treatments and 3 replications, that was P1 photoperiod 24 hours light (24L), P2 18 hours light (18L), P3 12 hours light (12L), P4 6 hours light (6L), P5 0 hours light (0L). The results showed that the difference in photoperiod had a significant effect on absolute length growth, absolute weight growth, and feed efficiency. Photoperiod 18 hours light (P2) is the best treatment that produces an absolute length growth of 0.94 cm, an absolute weight growth of 0.97 g and a feed efficiency of 38.31%. The photoperiod treatments applied in this study improved the growth performance of climbing perch fingerlings, however, they did not significantly affect blood glucose levels, survival rate, or water quality during the rearing period.
